Benefits of technology

The technology described in this patent provides a stereolithographic object that has good adhesion to a base member, but can be easily removed using a general remover without needing a dedicated curable resin. The object has two types of curable resin parts that differ in functional group number and polymer polymerization degree. The first curable resin part is easier to dissolve by the remover and helps create a void that allows for easier removal of the object. The second curable resin part is in contact with the base member in a small area, making it easier to remove compared to a case where it is in contact in a larger area. Overall, this technology allows for easy removal of stereolithographic objects without needing a dedicated curable resin.

Problems solved by technology

However, in methods disclosed in PTLs 1 to 3, dedicated curable resin is necessary and there has been an issue of low versatility.
It is to be noted that such an issue can arise independently of where to apply gel-state curable resin.

[0113][Configuration]

[0114]FIG. 5 illustrates an example of a cross-sectional configuration of a product 1 according to the first embodiment of the technology. The product 1 includes the base member 10 and a stereolithographic object 20 that is provided in contact with the surface of the base member 10. The base member 10 corresponds to one specific example of a “base member” and the “housing” of the technology. The stereolithographic object 20 corresponds to one specific example of a “stereolithographic object” of the technology. The surface of the base member 10 serves as a contact surface S with the stereolithographic object 20. The stereolithographic object 20 includes a base layer 21 provided in contact with the contact surface S, and a color layer 22 provided in contact with an upper surface of the base layer 21. The base layer 21 has a role as a base of the c...

Abstract

A stereolithographic object according to one embodiment of the technology includes: a first curable resin part that is provided at a position suitable for contact with a base member; and one or a plurality of second curable resin parts that are provided to be in contact with the first curable resin part and to allow part of a side surface of the first curable resin part to be exposed. The first curable resin part is configured by resin that has a functional group number and a polymer polymerization degree that are relatively small compared with those of the second curable resin part. The one or the plurality of second curable resin parts are configured by resin that has a functional group number and a polymer polymerization degree that are relatively great compared with those of the first curable resin part.

Description

TECHNICAL FIELD[0001]The technology relates to a stereolithographic object formed utilizing curable resin curable by light irradiation, a product, and a method of manufacturing a product.BACKGROUND ART[0002]In recent years, gel nails that involve curing of gel-state curable resin by ultraviolet light are popular. Recently, the number is increasing of people who enjoy putting on gel nails on fingers of their hands, feet, etc. not only in salons but also at home. The gel nails are characterized in that the gel nails have high adhesion characteristics with respect to nails and are easily kept for a long time. However, on the other hand, it is not easy to remove the gel nail. For example, it is necessary to damage a surface of the gel nail by scratching the surface of the gel nail with a nail file and thereby allow a remover to permeate the gel nail easily. Further, even in the case where the surface of the gel nail is damaged, it sometimes takes five minutes or longer to allow the remo...
